Due to the fourth of July holiday weekend, OSG support
resources will be limited so admins may want to wait until
Tuesday July 5th before updating.
This release contains the following updates:

* Several gatekeeper changes for CMS
* Optional re-nicing of the globus-gatekeeper to give it a
lower priority to keep the gatekeeper more responsive under heavy
loads
* Random sleep for fork jobs to prevent unwanted synchronization
of grid monitor processes

* Condor job manager changes to support group accounting
* SGE job manager changes to use a more reliable polling method
* Cleanup scripts are now provided by VDT so that files left by
globus in user home directories can be removed automatically

Several other updates are also included in this release, see
the VDT update page for more details.

Update Instructions
Update instructions can be found on the OSG Twiki under the OSG
1.2 update instructions ( https://twiki.grid.iu.edu/bin/view/ReleaseDocumentation/OSG12UpdateInstructions
).

release can be found here (

The LIGO VO (http://www.ligo.caltech.edu/) is looking for cycles. LIGO is currently running on approximately one-third of the OSG Resources and is ready to expand to more. Please take a look to see if your resource is enabled to allow LIGO VO jobs, and if it is not please consider enabling it. Below is a description of the application. LIGO has a strong application group that will work closely with resource providers to get the Einstein at OSG Application running. If you'd like to help please enable the LIGO VO and contact goc@opensciencegrid.org to let us know you'd like LIGO to run at your site. We are more than happy to provide assistance with enabling the VO or getting the application working on your site.

Einstein@OSG is software written to allow BOINC projects such as Einstein@Home to be executed in Grid environments. Initially developed at the Max-Planck-Institute for Gravitational Physics in Germany it is running today on the German D-Grid and the Open Science Grid. The software consists of a server scheduling and submitting jobs to grid resources and a client monitoring and executing the Einstein@Home client. Einstein@OSG has completed hundred's of million cpu hours on a vast number of heterogeneous grid resources mainly by utilizing available idle cycles.

E@OSG Execution on the OSG
--------------------------

The client supports following important features:

* ability to run on heterogeneous clusters providing i386 and x86_64 worker node architectures
* execution in $OSG_WN_TMP to avoid utilizing the network file system
* checkpointing on external SRM resources as well as network file systems such as NFS
* full support for eviction of jobs, automatic suspend and restart of the job
* automatic error detection and recovery of jobs
* support for GPU acceleration when available
* fine grained control about the client run-time (minutes to days) and scheduler (1 to 1000s of jobs)

which allows LIGO to utilize all compute elements currently available to LIGO to run jobs:

Please join us in welcoming the George E Brown Network for Earthquake Engineering Simulation (NEES) VO to the OSG community! NEES is a shared national network of 14 experimental facilities, collaborative tools, a centralized data repository, and earthquake simulation software. Together, these resources provide the means for collaboration and discovery in the form of advanced research based on experimentation and computational simulations of the ways buildings, bridges, utility systems, coastal regions, and geomaterials perform during seismic events.

OSG User Support has worked with this VO for several months by helping them integrate their applications with OSG. We would like to ask opportunistic sites to grant NEES access to resources. Information about their work and science is available at http://nees.org.

NEES has been recently added to the VO Package. We urge you to update to this new VO package to enable the NEES VO for opportunistic use. Instructions for doing this can be found here: http://osggoc.blogspot.com/2011/06/new-vo-package.html

Thank you in advance for your support of this new OSG VO.

At approximately 3:00pm Eastern time the Indiana University DNS administrators erroneously removed myosg.grid.iu.edu from their DNS servers. The service was unavailable at myosg.grid.iu.edu but could be reached via myosg1.grid.iu.edu and myosg2.grid.iu.edu. This problem was fixed by DNS administrators at 4:00pm Eastern time. We apologize for any inconvenience this has caused.

Between 14:50 and 15:10 UTC one instance of MyOSG (myosg2) experienced a spike in memory usage.
Some users may have encountered slow response times during this period. We believe the problem
was transitory in nature and is currently not effecting service. As a precaution, the effected
instance will be removed from DNS round robin at noon eastern time. The memory allocated to
this machine will be increased and the process repeated on the remaining instance. We do not
anticipate visible interruption of service during this process.

The GOC will upgrade the following services beginning at Tuesday, June 14th, 2011 at 14:00 UTC. The GOC reserves eight hours (14:00 - 22:00 UTC) in the unlikely event that unexpected problems are encountered. We encourage users to test affected services before the production release.
MyOSG 1.36

ITB version is now available for testing at https://myosg-itb.grid.iu.edu
Moved the Tiny URL button to the top of the page, and made it to generate TinyURL in a single click (and the URL pre-selected) [MYOSG-11]

GOC Ticket 1.37

ITB version is now available for testing at https://ticket-itb.grid.iu.edu
Renamed "Internal Activities" to "Footprints Activities", and renamed "Meta Information" to "Ticket Creation Information" in order to differentiate it from ticket metadata which are now key/value pairs stored in data.grid for each tickets.
Enabled shorter URL for ticket viewer (like.. https://ticket.grid.iu.edu/goc/10000)
Moved submitter DN information from update description to DB based metadata. Changed the layout for ticket viewer metadata in order to accommodate long value

GOC-Ticket Exchanger 1.19

Exchanging submitter DN between GGUS and Footprints so that ticket submitted through Footprints can be edited in GGUS via the same submitter.

OIM 2.35 (https://oim.grid.iu.edu)

ITB version is now available for testing at https://oim-itb.grid.iu.edu
Made Footprints ticket templates used during various registrations configurable via admin page [OIM-10]

Updated the WLCG flag labels so that their purposes are clear [old - OIM-53]
Made a service editor to be pre-inserted in a form during new resource registration.
Updated resource group selector inside resource registration form so that site & resource group can be selected independently in order to make it easier to specify resource group.
Added delete button inside Resource Downtime Editor.
Changed the way downtime records are “removed” by implementing ability to use "disable" flag instead of remove the downtime record physically.
Implemented GOCTicket metadata accesser with ability to set metadata (for SUBMITTER DN)
Various cosmetic changes.
